Dear Forum Users,
I've bought a MIMXRT1050-EVK board and started out with the uVision MDK by Keil. I've managed a few simple demos so far but have now inadvertently changed something and they can no longer be downloaded (rebuild works fine). I get the following error:
Load "sdram_debug\\emwin_gui_demo.out" No Algorithm found for: 00000000H - 0000FFFFH No Algorithm found for: 00010000H - 0001E733H Erase skipped! Error: Flash Download failed - "Cortex-M7" Flash Load finished at 17:29:53
I'm using the USB lead to program this board using the CMSIS-DAP debugger which is selected in <options>/<debug>
I've had this example running before but am now lost as to what has changed. I have moved the SW7 settings on the board but they are back as off-on-on-off again - this controls where the board boots from.
The board apparently has different RAM areas: 64MByte Hyperflash 32MByte SDRAM 8MByte QSPI Flash SD Card slot
512kByte onchip SRAM (on the i.MXRT1050 chip).
any pointers would be really appreciated.

Thank you for your fast reply. Unfortunately I don't quite understand still and would be very grateful if you could explain in a little more detail for me.
"The SDRAM download shouldn't be using the FLASH algorithms"... Is the Flash in addressess 0 onwards?
"the debug script (.INI) should be using LOAD command."... under PROJECT/OPTIONS/UTILITIES I have 'use Target Driver for Flash Programming' and the init file selected there is .\evkmimrt1050_ram.ini The other choice that seems listed is evkmimxrt1050_sdram_init.ini
"For writing to FLASH pick the correct project target"... When I load up the ecompass demo I can see the 'select target' drop down has four possibilities: ecompass_sdram_debug ecompass_debug ecompass_sdram_release ecompass_release I'm now selecting ecompass_debug - which I think will download to the flash memory.
"make sure you've selected the correct FLASH algorithm under the FLASH tab of the Debugger Settings"... under PROJECT/OPTIONS/DEBUG I have the CMSIS-DAP Debugger selected. If I click on Settings I get another window called CMSIS-DAP Cortex-M Target Driver Setup I can then select the FLASH DOWNLOAD tab which is what I think you are refering to? That has an algorithm for MIMXRT105x 64mB Hyper Flash selected. Erase sectors. Start=0x20000000 Size=0x00008000
My output has at least changed :-) FUNC void OnResetExec (void) { // executes upon software RESET Setup(); // Setup for Running } LOAD %L INCREMENTAL // Download Setup(); // Setup for Running ^ *** error 34, line 203: undefined identifier // g, main No Algorithm found for: 00000000H - 00006D4BH Erase skipped! Error: Flash Download failed - "Cortex-M7" Flash Load finished at 22:16:13
regards,
Well the zero memory isn't at 0x20000000, so you should probably Uncheck the "Update Target before Debugging" and/or "Load Application at Startup", so it uses the debug script rather than try to Flash the SDRAM/SRAM
Sure there are manuals, documents, examples where things are outlined.
Thank you again for your help - I think I can see where I'm going wrong now.
